roon 0.4.2

A modern node based python editor and REPL for physics, education, and data analysis

ROON

A node bsed editor for python using with a modern svelte frontend UI

Development

Svelte Application

Uses rollup + svelte For development (live reload etc.):

npm run dev

For a production build:

npm run build

Note: the .env file is used to set the python backend:

PYTHON_BACKEND=auto

Options are: auto, pyodide, pywebview, jupyter - but pywebview is the primary target with others to be implemented later. Pyodide works for a fully browser based implementation, but the filesystem (needed for any real data analysis) is only supported in chrome and edge.

Make sure that production builds for the python package are setup with pywebview - because it takes some time for the js bridge to fully load, the automatic detection of the backend is slower than being set directly.

note: the svelte app is setup to write out the build files to a custom directory for integration with python app (in the roon/static/ directory) instead of the standard public. So you need to symlink to make development builds available in browser (if you want to work in the browser)

ln -s roon/static/svelte/public public

Python application

Use makefile for installing development builds and for building the package for publication

dev-build:
	python -m pip install --editable .

build:
	python -m build

We use twine to publish the pypi package (use Makefile target check and publish) Twine uses authentication in $HOME/.pypirc for pushing to PyPi.
